Answer:
A. (x*2.5)*x
B. (32*2.5)*32=2560
Step-by-step explanation:
A = 30b
b = 8
a = 30(8)
a = 240 <== Ana has 240 stickers
Commutative property of additiona☺☺
1. -8x = 3x
-11x = 0
x= 0
y= 3(0)= 0
(0, 0)
2. -7x = -4x - 12
-3x = -12
x = 4
y = -7(4)= -28
(4, -28)
Sum of all interior angles of n-gon = ( n - 2) x 180.
Sum of all interior angles of 57-gon = (57 - 2) x 180 = 9900°
one angle = 9900 ÷ 57 = 173.68° (nearest hundredth)
---------------------------------------------
Answer : One angle = 173.68°
